Oocyte or ovarian tissue banking: decision-making in women aged 35 years or older facing age-related fertility decline

Balancing choice and socioeconomic realities: analyzing behavioral and economic factors in social oocyte cryopreservation decisions

Purpose

This research investigates the influence of personal income, the likelihood of pregnancy from cryopreserved oocytes, and the risk of infertility, on the decision-making process of women. The study employs the economic stated preference framework alongside the Theory of Planned Behavior in order to comprehend the process of decision-making.

Design/methodology/approach

The data had been collected from women between the ages of 18 and 65 via questionnaire employing conjoint analysis (CA). Through the utilization of this methodology, the factors influencing women's choices concerning oocyte cryopreservation were quantified.

Findings

The study identified crucial factors that impact the determination to cryopreserve oocytes, such as personal financial resources, the likelihood of achieving a successful pregnancy using frozen oocytes, and the potential for infertility. The analysis reveals that a considerable number of participants perceive cryopreservation as a feasible alternative for augmenting their prospects for future procreation.

Research implications

The results validate the patterns and the ways in which personal and socioeconomic elements impact choices regarding fertility. This has the potential to inform forthcoming health policies and educational initiatives that aim to provide more comprehensive support for women's fertility decisions.

Social implications

The research highlights the necessity of policy and societal support for women who are contemplating oocyte cryopreservation. It is recommended that public health policies incorporate provisions for state financing of cryopreservation in order to safeguard reproductive autonomy and alleviate the fertility risk linked to the aging process.

Originality/value

His research is unique in that it employs the Theory of Planned Behavior and an economic stated-preference framework to analyze the dynamics of oocyte cryopreservation decisions. This work enhances the existing body of literature by drawing attention to the socio-economic persona factors that influence choices regarding fertility preservation.

Social Freezing: Pressing Pause on Fertility

Increasing numbers of women are undergoing oocyte or tissue cryopreservation for medical or social reasons to increase their chances of having genetic children. Social egg freezing (SEF) allows women to preserve their fertility in anticipation of age-related fertility decline and ineffective fertility treatments at older ages. The purpose of this study was to summarize recent findings focusing on the challenges of elective egg freezing. We performed a systematic literature review on social egg freezing published during the last ten years. From the systematically screened literature, we identified and analyzed five main topics of interest during the last decade: (a) different fertility preservation techniques, (b) safety of freezing, (c) usage rate of frozen oocytes, (d) ethical considerations, and (e) cost-effectiveness of SEF. Fertility can be preserved for non-medical reasons through oocyte, embryos, or ovarian tissue cryopreservation, with oocyte vitrification being a new and optimal approach. Elective oocyte cryopreservation is better accepted, supports social gender equality, and enhances women's reproductive autonomy. Despite controversies, planned oocyte cryopreservation appears as a chosen strategy against age-related infertility and may allow women to feel that they are more socially, psychologically, and financially stable before motherhood.

Generation and assessment of high-quality mouse oocytes and embryos following nicotinamide mononucleotide administration

The low quality of oocytes is one of the main causes of the suboptimal reproductive outcome of female mammals with advanced maternal age. Here, we present a detailed protocol to obtain high-quality oocytes and embryos from aged mice by nicotinamide mononucleotide (NMN) administration. We also describe fluorescence staining procedures to assess the organelle dynamics in oocytes, and in vitro fertilization and embryo culture systems to evaluate the influence of NMN on the fertilization ability and embryonic development potential.

For complete information on the use and execution of this protocol, please refer to Miao et al. (2020).
